Alsijn

Alsijn (Arabic: السجن; lit. the prison) is a prison in a desert in an unknown location. It has reportedly been around for ages, home to many dangerous inmates and was regarded as virtually inescapable. However, one year after Hunter Radley was imprisoned there, a massive prison break occurred and Alsijn was partially destroyed. Hunter managed to escape but was forced to leave behind his friend Stan McClain. Stan escaped himself and reestablished himself in another city.
